Sometimes Kerio Connect may experience performance-related problems (CPU/RAM spikes, unstable overall User experience, system lags, etc.). This article provides information on how to monitor the system in-depth for Troubleshooting Performance Issues in Kerio Connect.
Prerequisites
- Kerio Connect being installed on Linux (Debian, Centos) or macOS, this article does not apply to Windows.

Glances is a Python made open source project for system monitoring.
- Open the Command Prompt or the Terminal app.
- Type the following command.
glances -export csv -export-csv-file "~/location/file.csv"
Replace~/locationwith your actual folder name. This command exports all the results into a CSV file. - Observe the reported issue while the Glances tool is running.
You might leave the tool running while experiencing the issue a couple of times. Please capture the exact date and time of the performance-related issues (RAM/CPU drops, system glitches, etc.) that you are experiencing. - Supply the above information, along with the resulting CSV file to the Support Team for further assistance.
